... Chemical bonds A. Electron energy is shared or donated B. Only valence electrons involved in chemical bonds (Octet rule) C. Ionic bonds – electrons are transferred from one atom to another, forming ions. Ions of opposite charge attract forming an ionic bond D. Most ionic compounds are salts E. Coval ...

Period #2 Notes: Electronic Structure of Atoms
... The three prior types of bonding (ionic, covalent, metallic) are the primary ones in that they form “stable” compounds in which the net charge balances are satisfied. Often, the molecules of the stable compounds formed by primary bonding mechanisms, while having no net charge, will have some polarit ...

Adhesion
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article.
